This physics video tutorial explains the concept of basic electricity and electric current. It explains how DC circuits work and how to calculate voltage, current, and electrical resistance using Ohm's law. In addition, it shows you how to calculate the electric charge and the number of electrons flowing through a wire at any given point. In addition, it has a few examples and practice problems on electric power, cost of electricity in Kwh and other stuff as well. It provides visual drawings, equations, and formulas as well as the units of common variables that you'll encounter when dealing with electricity. It discusses the difference between conventional current and electron flow. The unit of electric current is the ampere or amps for short. The unit for resistance is ohms and for voltage is volts. 1A is 1C/s or 1 coulomb per second. Electric current is the rate of electric charge flow. Charge represents the quantity of electrons in the case of metal conductors. The unit of power is the watt which is 1 Joule per second. Power is the rate at which energy is transferred. Equations used include V=IR, P=VI, and Q=It.

If 360 coulomb charge flows a conductor in 3 minutes, calculate the current flowing through a circuit.

There are several factors in learning circuits. One plan I discovered which successfully combines these is the Gregs Electro Blog (google it if you're interested) without a doubt the best course that I've heard of. look at this interesting resource.

I'm an old engineer who hasn't had the need for this stuff for years due to the kind of assignments and opportunities that were offered to me out of school. Now I'm refreshing my old self. It's so weird to see stuff that I learned 20 years ago just pop back with a little nudge from these videos. A great way to learn or relearn.

How v=IR? Because if v=IR so resistance will directly related with v and you said that the voltage inversaly related with R .I hope to clear that point for me and thank you for this amazing explain

What would happen if there were onlybprotons and newtons and no electrons?
WhoistheJC? 4 months ago
If there were only protons and neutrons there would be no chemistry, no molecules, no chance of life. Matter would never clump together.

thanks a lot dude ..Its the first and last test of 8th grade..we have never had a test in physics and the first time we have I don't wanna fail..and you teach sooo damn well...btw you know the physics teacher sucks
